Did you ever notice the wheels on the car driving next to you sometimes appear to be spinning backwards? This is referred to as the stroboscopic (or wagon-wheel) effect. It occurs when an object is rotated at certain speeds, making the object to appear to stop or even go backwards. Rotate 4 different objects in either direction (clockwise or counterclockwise). You can increase the speed until you see it appear to stop or reverse. On one of the objects, a wheel with different colored alternating rings, you can make it appear as if the rings of this single option are turning in opposite directions. Universal App - supports native iPad, iPhone and iPhone 4's Retina display. WARNING - Those with Epilepsy or those subject to seizures are usually cautioned to avoid strobe lights or similar effects.

This is a 3D animation in which the sun, the earth, and the moon rotate. -You can change the rotation speed. The fastest is 1 second, and the slowest is 300 seconds to make one revolution. -It can rotate in the reverse direction, which is not possible in the natural world. -The earth and the moon can change the light from the sun by 30 degrees. -There are three types of earth: night lights, nature, and globes.

Verdict
The clearest difference is price: Stroboscopic Effect at Free against Earth Rotation's $0.99. Stroboscopic Effect also leads on ratings volume (18 vs 1) and iOS requirement (8.0 vs 15.0). Earth Rotation's advantage is rating (5.0 vs 2.7) and update cadence (every 22 months vs every 84 months). On ads, in-app purchases and device support there is nothing between them.
